There are difficulties in the translation, the question being whether the wrath mentioned belongs to Job or to God. The verb translated ‘deliver’ means ‘entice’, ‘allure’, or ‘take away’.
The greatest blessings may come through chastisement. Every one of us will be lifted up to dizzy pride, but if we humble ourselves we will receive the greatest blessing. In the Middle Ages we would probably have all been serfs, but now we live in an age of magnification. Satan’s strategy changes. All are now made to feel so important and that we should be at the centre of our lives with all others looking to us. When God humbles us through great chastisement it may lead, as in the case of Job, to greatest blessing.
When angry, we are denying what God has told us. Be careful you don’t consider the possibility of turning to iniquity. In trials we begin to think, ‘If only I could do what the world does, perhaps it will help. If I resorted to a lie; if I cut a few corners, I would relieve the pressure I am under’. That is not an option for the believer. Even as a child of God, you may behave so badly that God turns his face from you. Likewise Job could be so foolish that God would not rescue him in this life. It is a solemn warning.
